What is true of an object that is in free fall?
no forces are acting on it.
the forces of thrust and gravity balance one another.
the forces of air resistance and gravity balance one another.
only the force of gravity is accelerating it.

one is through turgidity. this occurs before ground tissue ( collenchyma

and sclerenchyma cells) become well

developed to give structural support to the plant as it grows bigger. the xylem

tissue (composed of rigid tissue) of the young

plant render this support and also maintaining osmotic turgidity of the surrounding

plant cells.
